Updating Finite Element Model of a Wind Turbine Blade Section Using Experimental Modal Analysis Results
Abstract
This paper presents selected results and aspects of themultidisciplinary and interdisciplinary research oriented for the experimental and numerical study of the structural dynamics of a bend-twist coupled full scale section of awind turbine blade structure.Themain goal of the conducted research is to validate finite elementmodel of themodified wind turbine blade section mounted in the flexible support structure accordingly to the experimental results. Bend-twist coupling was implemented by adding angled unidirectional layers on the suction and pressure side of the blade. Dynamic test and simulations were performed on a section of a full scale wind turbine blade provided byVestasWind Systems A/S.Thenumerical results are compared to the experimental measurements and the discrepancies are assessed by natural frequency difference andmodal assurance criterion. Based on sensitivity analysis, set ofmodel parameters was selected for the model updating process. Design of experiment and response surface method was implemented to find values of model parameters yielding results closest to the experimental.The updated finite element model is producing results more consistent with the measurement outcomes.
